MACHINE FOR rnnnmo' nnannn BLANKS. Application filed September 6, 1923. Serial No. (31,210.

This invention relates to machines for aurim of the bucket wheel 21 and is provided 55 tomatically feeding headed blanks with their with a flat rear section parallel to the plane headed ends upward, and more particularly to of the bucket wheel. Each bucket 27 is roi a blank feeding machine inwhich a series of vided at its forward end with a laterally ina blanks are continuously fed upon an inclined clined end wall adapted to deflect blanks to chute from a rotary bucket Wheel, which is Ward the front of the bucket wheel. The 60 mounted to rotate in a plane at right angles to. 1 buckets 27 are adapted to pick up blanks from the ch t the hopper while the buckets are traveling One object of the invention is to provide a upwardly, and to discharge the blanks into 10 device of the above nature which will be simthe chute 19 when traveling downwardly.

The bot- 'connected to the front face 16 of the hopper. tom section 11 is adapted tobe supported upon A kicker or blank-re ecting wheel 43 is a hopper bracket 12, as clearly shown in Fig. also mounted on said shaft 41, and is adapted 2, said bracket 12 being provided with a to be positioned slightly above the chute 19 at 85. flanged base 13 secured to the platform 14 of the polnt where said chute passesthrough said the machine to which the blanks are to be fed, hopper. The wheel 43'has a notched groove in in any suitable manner, as by means of bolts 15 its circumference which just receives the 3 and 16. heads of blanks which lie in proper position The hopper is provided at the front with a in the chute 19 and permits them to s i down 90 vertical upper face below which is an inclined freely.

In order as vided with a peripheral flange 20 against to prevent the properly positioned blanks which a rotary blank feeding bucket'wheel 21 which pass under the kicker wheel from beis adapted to fit. The bucket wheel 21 is ing accidently jolted out of the chute by the mounted on a stud shaft 22 supported by a vi ration of the machine, a cover rail 44 is bearing standard 23. The standard 23 has 11 provided, said cover rail being secured to said 100 flat front section 24 secured to the base 13 by chute by angle brackets .45 and screws 46. bolts 25. The rear end of the shaft 22 beyond One advantage of the present invention lies the standard 23 is provided with a hand wheel in the fact that the bucket wheel is located at 26 by means of which the bucket wheel 21 may the end of the chute and at right angles therebe manually rotated whenever desired.
